There appears to be some separation in quarterback play for the Arizona Cardinals and their division rivals in recent weeks.
I'll take a closer look later Monday.
In the meantime, here are a couple charts to digest. They show quarterback stats for all NFC West players attempting passes since Week 8. That was the week Alex Smith completed 18 of 19 attempts against Arizona in the Monday night game.
Smith ranks fourth in Total QBR since Week 8 among players with enough plays to qualify for season-to-date rankings. Seattle's Russell Wilson ranks second. Tom Brady is first. St. Louis' Sam Bradford is 15th. Again, that's all since Week 8.
Smith leads the NFL in passer rating since Week 8 (153.2) among qualifying QBs. Brady is second (117.5), followed by Wilson (115.2), Peyton Manning (108.0) and Drew Brees (107.8). Smith would rank higher in QBR over that span if he did not rank last among these passers in average pass length (4.9 yards), under the 8.2-yard average for the others.
